The "Kocktails with Khloe" host took to Instagram to share a lengthy post about unrequited love, leading many to believe that she is talking about her former partner Lamar Odom, reports aceshowbiz.com.

"It doesn't matter how loyal you are to someone. You can't change someone's heart and bad habits unless they want to themselves," read the quote she posted.

After reading the quote, many speculated that the 31-year-old star was talking about Odom, who was recently caught drinking again after suffering drug overdose in October 2015.

"Letting go doesn't mean that you don't care about someone anymore. It's just realising that the only person you really have control over is yourself," she wrote in the caption, adding that people were not supposed to take care of other people's business.

As she shared that she believed "timing is everything", the "Keeping Up With the Kardashians" star continued: "People say time heals all wounds... I say time heals wounds but scars are left to remind you what you have been through and what you survived. Stop shattering your own heart by trying to make a relationship (friend, family, partner) work that clearly isn't meant to work...Sometimes the person you want most is the person you're best without."
